 In the case of necrotrophic pathogens, HR might even be beneficial to the pathogen, as they require dead plant cells to obtain nutrients.The situation becomes complicated when considering pathogens such as "Phytophthora infestans" which at the initial stages of the infection act as biotrophs but later switch to a necrotrophic lifestyle.It is proposed that in this case HR might be beneficial in the early stages of the infection but not in the later stages.
